Issue #480 has been updated by Martin Roth.
Tracker changed from Bug to Cleanup
As these are remarks, it would certainly be nice if they were fixed, but I can't call this a bug, even if it isn't efficient.
Changing from Bug to Cleanup. Leaving priority as normal, because I agree with Paul that this should be addressed.
---------------------------------------- Cleanup #480: amd/common/acpi/gpio_bank_lib.asl: IASL remarks: Creation of named objects within a method is highly inefficient, use globals or method local variables instead https://ticket.coreboot.org/issues/480#change-1519
* Author: Paul Menzel * Status: New * Priority: Normal * Target version: none * Start date: 2023-04-10 * Affected versions: master ---------------------------------------- Building AMD boards using AMD common code like *google/kahlee (Careena)* or *google/myst*, IASL show the remarks below:
